Description

하이브리드 차량의 작동 방법 및 상기 방법의 실시를 위한 제어 장치{METHOD FOR OPERATING A HYBRID VEHICLE, AND CONTROL UNIT FOR CARRYING OUT THE METHOD}METHOD FOR OPERATING HYBRID VEHICLE, AND CONTROL UNIT FOR CARRYING OUT THE METHOD}

본 발명은 청구범위 제1항의 전제부에 따른, 하이브리드 차량의 작동 방법 및 청구범위 제9항의 전제부에 따른, 상기 방법의 실시를 위한 제어 장치에 관한 것이다.The present invention relates to a method of operating a hybrid vehicle according to the preamble of claim 1 and to a control device for the implementation of the method according to the preamble of claim 9.

차량의 제어 장치에는 회전수를 조절하기 위한 알고리즘이 있다. 이러한 조절 시스템의 중요한 과제는 기준을 밑돌지 않는 일정한 아이들링 속도를 설정하는 것이다. 내연 기관이 구비된 종래의 차량에서는 상기 조절 시스템이 상응하여 제어된다. 추가로, 내연 기관 이외의 구동 장치들, 특히 적어도 하나의 전동기를 가지고 있는 하이브리드 차량을 위해 목표 회전수를 설정하기 위한 추가의 장치 또는 장치들이 또한 포함될 수 있다. 상기 방법은 예를 들어 이미 DE 10 2004 06 012 에 제안되었다.The control device of the vehicle has an algorithm for adjusting the rotation speed. An important challenge of this control system is to set a constant idling speed that does not fall below the standard. In a conventional vehicle equipped with an internal combustion engine, the regulation system is correspondingly controlled. In addition, additional devices or devices may also be included for setting target rotational speeds for drive devices other than internal combustion engines, especially for hybrid vehicles having at least one electric motor. The method has already been proposed for example in DE 10 2004 06 012.

본 발명은 적어도 두 개의 구동 장치 중 적어도 하나가 내연 기관인 하이브리드 차량의 작동을 위해 회전 토크를 제공하는 하이브리드 차량의 작동을 위한 방법에 관한 것이며, 상기 방법에서 필요한 전체 리저브 회전 토크가 검출되고 각 개별 구동 장치들의 실제 제공 가능한 리저브 회전 토크의 한계가 결정된다. 바람직하게 종래의 PID 조절기로써 실행될 수 있는 회전 속도 조절기가 설치된다. 종래의 차량에서 조절 신호의 비례, 적분, 미분 성분의 총합은 내연 기관에 의해 조절되는 반면, 하이브리드 차량에서 상이한 조절기 성분들은 내연 기관 및 예를 들어, 하나의 전동기 또는 다수의 전동기들에 분배될 수 있다. 가능한 분배는 내연 기관에서 적분 성분의 구현을 제공하며, 예를 들어, 내연 기관 및 전동기에서 성분들에 대한, 조절기의 전체 증폭의 분배(전체 비례 성분 및/또는 상황에 따라 전체 미분 성분)를 제공한다. 동시에 바람직하게 분배의 경우 가능한 구동 장치의 제어 변수를 제한하는 것이 고려된다. 상기 방법으로 회전 토크를 제공하는 경우의 문제점들이 바람직하게 방지된다. 상기 방법으로, 예를 들어 오토 엔진은 적합한 점화 각도 간섭을 통해 모멘트를 신속하게 감소시키는 제어 요구를 문제없이 구현할 수 있지만, 모멘트를 신속하게 증가시키는 제어 요구는, 적시에 미리 적합한 모멘트 유도가 공기 충전의 상승을 통해 동시에 점화 각도를 조절하면서 실시되는 경우에만 구현될 수 있다. 예를 들어 축전기로서 배터리가 잠시 동안 에너지를 충분히 제공할 수 없거나 수용할 수 없을 때, 또는 상응하는 최대 모멘트 또는 최소 모멘트가 이미 소진되었을 때, 전동기는 이와 유사하게 거동한다.The present invention relates to a method for the operation of a hybrid vehicle that provides a rotational torque for the operation of a hybrid vehicle in which at least one of the at least two drive units is an internal combustion engine, wherein the total reserve rotational torque required in the method is detected and each individual drive is performed. The limit of the actual available reserve rotational torque of the devices is determined. Preferably, a rotational speed regulator is installed which can be implemented as a conventional PID regulator. In conventional vehicles, the sum of the proportional, integral, and derivative components of the regulation signal is controlled by the internal combustion engine, while in the hybrid vehicle different regulator components can be distributed to the internal combustion engine and, for example, one motor or multiple motors. have. Possible distributions provide for the implementation of the integral component in the internal combustion engine, for example, the distribution of the overall amplification of the regulator (total proportional component and / or the total derivative component, as appropriate), for components in the internal combustion engine and the electric motor. do. At the same time it is advantageously contemplated to limit the control variables of the drive device which are possible in the case of distribution. Problems when providing rotational torque in this way are preferably avoided. In this way, for example, an Otto engine can implement a control request that quickly reduces the moment through suitable ignition angle interference, while a control request that quickly increases the moment is timely and appropriately appropriate induction of the moment induces air charge. It can only be implemented if it is carried out while simultaneously adjusting the ignition angle through the rise of. The motor behaves similarly when, for example, a battery as a capacitor cannot provide enough energy or accept it for a while, or when the corresponding maximum or minimum moment has already been exhausted.

바람직하게 포괄적인 회전수 코디네이터에 의해 필요한 전체 리저브 모멘트가 검출되며, 이 리저브 모멘트는 가장 짧은 시간 내에 호출되며, 따라서 필요한 경우에는 내연 기관의 비례 성분 또는 미분 성분에 의한 총합으로 그리고 전동기(또는 다수의 전동기)의 비례 성분 또는 미분 성분에 의한 총합으로 신속하게 조절될 수 있다.Preferably the total reserve moment required by the comprehensive speed coordinator is detected, which reserve moment is called in the shortest time, and therefore, if necessary, in sum by the proportional or differential component of the internal combustion engine and the motor (or a plurality of It can be adjusted quickly by the sum by the proportional component or the derivative component of the electric motor).

이에 병행하여 관여하는 모든 구동 장치들을 위해 실제 가능한 리저브 회전 토크의 한계가 계산될 수 있다. 특히 전기 구동을 위해 전동기의 최대 회전 토크 및 최소 회전 토크와, 예를 들어 축전기를 통해서와 같은, 제한이 고려된다. 내연 기관에서 리저브 회전 토크는 동시에 점화 각도가 지연 조절되는 경우, 공기 충전이 상승됨으로써 실현될 수 있다. 점화 각도 지연을 이용한 모멘트 감소는 내연 기관 내에서 연소되는 연료의 가연성 한계를 통해 제한된다. 이를 통해 내연 기관의 실제 가능한 리저브 회전 토크를 위한 한계가 제공된다.In parallel a limit of the actual possible reserve rotational torque can be calculated for all drive devices involved. In particular for electric drive the maximum and minimum rotational torques of the electric motor are constrained, for example via a capacitor. The reserve rotational torque in the internal combustion engine can be realized by raising the air charge when the ignition angle is delayed adjusted at the same time. Moment reduction with ignition delay is limited through the flammability limits of the fuel combusted in the internal combustion engine. This provides a limit for the actual possible reserve rotational torque of the internal combustion engine.

이어서 상기 정보에 기초하여 구동 장치들에 대한 전체 리저브 회전 토크의 요구되는 분배가 실행될 수 있으며 구동 장치들은 상응하게 제어될 수 있다. 이에 병행하여 전체 비례 증폭 및 전체 미분 증폭이 내연 기관 및 전동기(들)에 분배될 수 있으며, 구체적으로 전체 리저브 회전 토크의 분배에 상응하여 분배된다. 전동기가 리저브를 형성할 수 없기 때문에 예를 들어 전체 리저브 모멘트는 내연 기관을 통해 100% 제어되므로, 전체 비례 증폭 또는 전체 미분 증폭도 오로지 내연 기관을 통해서만 조절되어야 하고 그 반대도 마찬가지다. 상술한 극한값 사이의 분배를 위해 목적에 맞도록 적합하게 보간될 수 있다.Based on this information, the required distribution of the entire reserve rotational torque for the drive units can then be carried out and the drive units can be controlled accordingly. In parallel to this, total proportional amplification and total differential amplification can be distributed to the internal combustion engine and the motor (s), in particular corresponding to the distribution of the total reserve rotational torque. Since the motor cannot form a reserve, for example, the total reserve moment is 100% controlled by the internal combustion engine, so that the total proportional amplification or the total differential amplification must be controlled solely through the internal combustion engine and vice versa. It can be interpolated suitably for the purpose for the distribution between the above-mentioned extreme values.

안정된 조절은 신속한 제어 조치의 가능한 이용을 통해 모든 분배된 구동 장치들의 총합으로 달성된다. 전기 기기의 리저브의 완전한 이용을 통해 오토 모터에서 효율이 감소하는 점화 각도의 간섭이 감소 될 수 있다.Stable regulation is achieved by the sum of all distributed drive units through the possible use of quick control measures. Through the full use of the reserve of the electrical appliance, interference in the ignition angle, which reduces efficiency in the auto motor, can be reduced.

상술한 방법의 특별한 장점에 따르면, 항상 효율 저하 및 연비 저하와 결부되는 내연 기관의 리저브 모멘트를 방지하기 위해, 가능한 최적화된다. 이를 위하여 우선 전기 기기의 리저브 퍼텐셜이 완전 소진되고, 가능한 한, 전체 리저브 모멘트 및 상응하는 전체 비례 증폭 또는 전체 미분 증폭이 전기 기기에 의해 구현된다. 이 경우 내연 기관을 통한 리저브 모멘트가 요구되지 않으며, 따라서 점화 각도 간섭도 요구되지 않을 것이다. 단지 전기 구동의 제어 범위가 소진될 때, 신속한 간섭을 이용하여 조절 회로의 안정성 및 성능을 보장하기 위해 내연 기관이 사용된다.According to the particular advantage of the above-described method, it is possible to be optimized as possible in order to prevent the reserve moment of the internal combustion engine, which is always associated with lowering efficiency and lowering fuel economy. For this purpose, the reserve potential of the electrical appliance is first exhausted and, as far as possible, the total reserve moment and the corresponding total proportional or total differential amplification are realized by the electrical appliance. In this case no reserve moment through the internal combustion engine is required, and therefore no ignition angle interference will be required. Only when the control range of the electric drive is exhausted, an internal combustion engine is used to ensure the stability and performance of the regulating circuit with rapid interference.

내연 기관이 아닌, 적합한 전체 증폭을 최대로 광범위하게 구현하는 하나 또는 다수 구동 장치의 리저브 회전 토크가 우선 소진되는 것이 바람직하다. 상기 구동 장치/구동 장치들의 제어 범위가 소진되는 경우 내연 기관이 사용될 수 있다.It is preferred that the reserve rotational torque of one or multiple drive units, which, rather than internal combustion engines, realize the widest possible range of suitable overall amplification, is first exhausted. An internal combustion engine can be used when the control range of the drive / drive devices is exhausted.

이하, 본 발명은 실시예에서 관련 도면에 의해 상세히 설명된다.The invention is now described in detail by the relevant figures in the Examples.

도1은 하이브리드 차량을 작동하기 위한 방법의 진행 과정을 도시한다.1 shows the progress of a method for operating a hybrid vehicle.

도면에는 도시되지 않은, 차량 구동에서의 구동 장치로서 내연 기관과 전동기를 구비하는 바람직한 하이브리드 차량에 있어서, 본 발명에 따른 방법의 진행 과정이 도시된다. 두 개의 구동 장치들은 하이브리드 차량의 구동을 위한 회전 토크를 제공한다. 이는 일시적으로 동시에 실행될 수 있거나, 일시적으로 각각 하나의 구동 장치가 요구되는 회전 토크를 단독으로 공급될 수 있다.In a preferred hybrid vehicle having an internal combustion engine and an electric motor as a driving device in driving a vehicle, which is not shown in the drawings, the process of the method according to the invention is shown. Two drive units provide rotational torque for driving the hybrid vehicle. This may be carried out temporarily at the same time, or may be temporarily supplied with the rotational torque each one drive device is required.

필요한 전체 리저브 회전 토크와 회전수 조절기의 조절기 전체 증폭은 제1 진행 단계(10)에서 결정된다. 상기 방법은 바람직하게 본 발명에 따른 제어 장치에서 진행된다. 전체 리저브 회전 토크는 예를 들어 운전자의 요구에 의해, 또는 냉난방장치와 같은 소모 장치의 연결에 의해, 또는 실제의 회전수에 따라 결정될 수 있다.The required total reserve rotational torque and regulator overall amplification of the speed regulator are determined in the first progression step 10. The method preferably proceeds in a control device according to the invention. The total reserve rotational torque can be determined, for example, at the request of the driver, by the connection of a consuming device such as a heating and cooling system, or according to the actual rotational speed.

조절기 전체 증폭은 비례 성분(P 성분)과 경우에 따라 미분 성분(D 성분)을 포함한다. 회전수 조절기로써 PID 조절기가 설치되며, 적분 성분(I 성분)은 바람직하게 내연 기관에서 구현될 수 있다.The overall regulator amplification includes a proportional component (P component) and optionally a derivative component (D component). As the speed controller, a PID controller is installed, and the integral component (component I) can preferably be implemented in an internal combustion engine.

후속적으로 제2 진행 단계(12)에서, 예를 들어 내연 기관 및 전동기 등 모든 이용 가능한 구동 장치의 가능한 회전 토크 리저브의 한계가 계산된다. 동시에 구동 장치의 제어 변수의 제한이 포함된다.Subsequently in the second running step 12, the limits of the possible rotational torque reserves of all available drive devices, for example internal combustion engines and electric motors, are calculated. At the same time the limitations of the control variables of the drive system are included.

다음 진행 단계(14)에서 전체 리저브 회전 토크의 분배와 구동 장치들에 대한 조절기 전체 증폭의 분배가 이루어진다.In the next step 14 the distribution of the total reserve rotational torque and the distribution of the regulator total amplification to the drive devices are made.

후속적으로 바람직한 병렬 진행 단계(16 및 18)에서는 전체 회전 토크 리저브에 대한 내연 기관의 성분을 갖는, 내연 기관 및 전체 회전 토크 리저브에 대한 전동기의 성분을 갖는 전동기가, 0% ~100% 범위 내에서 전체 증폭의 각각의 P 성분 및/또는 D 성분으로 작동된다.Subsequently in the preferred parallel running stages 16 and 18, the motor having the component of the internal combustion engine for the total rotational torque reserve and the component of the electric motor for the total rotational torque reserve is in the range of 0% to 100%. At each P component and / or D component of the total amplification.

이러한 경우, 우선 전동기의 리저브 회전 토크가 소진되고 상응하는 전체 증폭은 상기 구동 장치를 사용하여 광범위하게 구현된다. 상기 구동 장치의 제어 범위가 소진되는 경우 내연 기관이 사용된다.In this case, first the reserve rotational torque of the motor is exhausted and the corresponding overall amplification is widely implemented using the drive device.
